Victoria 310 (Sutherland 100, Harris 85, Grant 4-82) and 0 for 6 lead South Australia 230 (Head 76, Carey 70, Sutherland 4-45, Boland 4-60) by 86 runs
Boland was a key figure as he led Victoria to a position of dominance at the midway point of the Sheffield Shield match against South Australia in Adelaide.
Victoria ended a rain-impacted day two at Karen Rolton Oval with a lead of 86 runs after dismissing South Australia for 230 late in the day.
It was a much-needed recovery for the home side who were left reeling at 3 for 30 after Boland's early impact.
Boland squared up reliable opener Jake Weatherald in the second ball of the innings to offer a simple catch at gully. The Test quick had figures of 3 for 24 from 12 overs having also knocked over Henry Hunt and Jake Carder in his opening spell.
Allrounder Sutherland collected the other top-order wicket to fall by dismissing Jake Lehmann for 28. It was another successful day for Sutherland who hit his maiden first-class century on day one.
Boland even inflicted pain on South Australia with the bat adding 50 for the last wicket in concert with No. 11 Jon Holland.
Victoria resumed at 9 for 264 but Boland (24 not out) and Holland (28) lifted the visitors to 310. SA paceman David Grant eventually ended the home side's pain, collecting his side's best figures in the process.
